Abstract
A valve operating device for an engine is provided. The device includes at least two cam elements per one shaft. End face cams are formed in opposing end faces of two adjacent cam elements, and the end face cams respectively have protruding portions being formed offset in phase so that the protruding portions overlap in the axial directions when the two cam elements are close to each other. A control member is provided, the control member is projected to an actuated position at which the control member is projected to engage with the end face cams so as to separate the adjacent cam elements from each other when the cam elements are close to each other, and the control member is retreated to a non-actuated position at which the control member is retreated from the actuated position.
